Does flipping an animated GIF break the animation?

No. Each frame is decoded, the pixel grid is mirrored along the chosen axis, and the frame is re-encoded into the output stream with its original Graphic Control Extension still attached. The per-frame delays (stored in hundredths of a second) and the Netscape Application Block loop count (1–65535 or infinite) carry through unchanged, so the flipped GIF plays at the same speed and loops the same number of times as the source.

What is the difference between flipping and rotating a GIF?

Flipping mirrors the image across an axis — horizontal mirrors left↔right, vertical mirrors top↔bottom — and is its own inverse. Rotating turns the image by an angle and changes its orientation rather than mirroring it. A 180° rotation looks pixel-identical to applying both a horizontal and a vertical flip, but a 90° or 270° rotation cannot be reproduced by any combination of flips. For angle-based turns, use Rotate GIF.

Will the file size change after flipping?

Usually only by a small amount. The pixel data is reshuffled but the palette, frame count, and timing don't change, so the LZW-compressed payload ends up nearly identical in length. Expect a few percent up or down depending on how the new pixel order interacts with the LZW dictionary. If you want a noticeably smaller file, drop the palette size, lower the resolution, or run Compress GIF afterwards.

Does the flipper handle partial transparency, like a faded edge?

Not directly — that's a limitation of the GIF format, not the flipper. GIF89a supports only 1-bit transparency: every pixel is either fully opaque or fully invisible via a single transparent index in the palette. Semi-transparent edges from the source (common when converting from PNG or WebP) are already snapped to opaque-or-transparent before they reach the flipper. If you need true alpha, flip in PNG or WebP instead.

Can I flip and resize at the same time?

Yes. Set the flip direction, then expand Image Resolution and pick a preset (e.g., 480p), enter a custom Width/Height, or scale by percentage. Flip and resize run in the same encoding pass, which avoids the small palette drift you can get from re-encoding twice. Reducing resolution also trims file size for large animated GIFs.

Why does my horizontal flip look identical to the original?

The GIF is probably already symmetric along the vertical axis, or the asymmetric part (text, a face, a logo) sits very near the center. Try a vertical flip to confirm the tool is running; if vertical changes the image but horizontal doesn't, the source is genuinely left-right symmetric. For text overlays, the letters themselves will flip and become unreadable — that's expected behavior, not a bug.

Will flipping fix a Live Photo–derived GIF that looks "wrong-handed"?

Yes, in most cases. iPhone Live Photos are 1.5-second 15 fps clips that, when exported as a Loop or Bounce GIF or via the Shortcuts "Make GIF" action, contain roughly 22–30 frames. The front-camera preview is mirrored on screen but saved un-mirrored, so the resulting GIF can look reversed compared to what you saw. A single horizontal flip puts text, parted hair, and logos back in the orientation you remember.

Can I flip a static (single-frame) GIF?

Yes. The tool detects single-frame GIFs and applies the flip to that one frame, preserving palette, transparent index, and dimensions. The output is still a valid.gif file. If you want a different container, convert to PNG or WebP afterwards.

Are my uploads sent to a server or shared?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. No account is required, there are no watermarks, and there is no upload size paywall for typical viral-GIF dimensions (under ~10 MB).
